5 Gasket Seals

6 Gasket Seals Gasket applications cover a large spectrum of materials ranging from acrylic and aluminum to Viton and Teflon. Your gasket manufacturing options are as varied as Die Cutting and Lathe Cutting to Pressure Sensitive Adhesives and Vulcanization. Vedovell has over 40 years of gasket experience, working with the materials listed below for a wide range of applications. We understand the importance of a proper gasket and the cost considerations. One very cost effective method of cutting gaskets is utilizing steel rule dies; others are lathe-cutting and thropcutting. Not all methods will produce the same tolerances and some materials only lend themselves to certain methods of manufacturing. Perhaps you have a critical dimension, this may require a hardened steel tool or perhaps it will be best produced by water jet cutting or even molding. Let Vedovell be the source for all your gasket requirements. Contact Vedovell and we will put our experts to work for you. Our knowledgeable sales staff will assist you in pairing the right gasket material with the right manufacturing process. Slitting, pressure sensitive adhesives, assembly and special packaging are some of the additional services supplied. Vedovell will quote on both long and short run die cut products.

7 O-ings

8 O-ings The O-ring is the most widely used seal in industry. It is easy to install, can be used as a double-acting seal, can seal pressures to over 5,000 psi in static and dynamic applications and is very economical. While simple in concept, the O-ring can be sophisticated in application. The information in this catalog is intended to give a brief overview of O-ring design and selection. Specifying O-rings O-rings are specified by calling out the O-ring size, and the compound. 0-rings are available in 349 sizes as set up by the Aerospace Standard 568 published by the Society of Automotive Engineers. These sizes are designated by dash numbers as shown on the 568 DASH Chart. For instance, an O-ring with an inside diameter (I.D.) of and a cross section (W) of is designated as: AS Compound Selection Compounds are available in a variety of elastomers such as Nitrile, Neoprene, Ethylene Propylene, Fluoroelastomer, etc. To select the proper elastomer, check the following in properties: Fluid Compatibility Chart Temperature ange Chart General Elastomeric Properties For O-ring sizes other than standard sizes, specify the actual dimensions desired for the inside diameter (I.D.) and the cross section (W). There may be a tooling charge for such non-standards. sually you will be able to find one best base elastomer to meet these requirements. The next step is to determine the durometer (hardness) needed, from the Durometer-Pressure-Gap Chart (see Properties section) James St. Zeeland, I 49464, SA

11 Encapasulated O-ings A circular shaped seal with a round cross section consisting of two components, a Teflon jacket and an internal (core) energizer, which imparts memory to the seal. The encapsulated O-ring is intended to close off potential leak paths between mating surfaces in both static and dynamic applications. Encapsulated O-rings are offered in two Teflon grades, FEP and PFA with a selection of three different energizers which give the user a choice depending on temperature and operating environment. Teflon grades FEP The most versatile when considering overall corrosion resistance, sealing capability and temperature. Temperature range -450 F to +400 F (-267 C to 205 C). PFA A fluorocarbon copolymer similar to FEP but it also offers greatly improved mechanical and creep properties at elevated operating temperatures. Temperature range -450 F to F (-267 C to +260 C). Features When considering the encapsulated concept, one should take into account the many features which FEP and PFA Teflon have to offer: Corrosion resistance ltra low moisture absorption niformity Low cold flow Broad temperature range Good dialectic properties Flexibility Low coefficient of friction Permeation resistance Abrasion resistance Non-flaable Good impact strength Excellent resilience Lubricity No swelling eusable FDA Approval The nited States Federal Food and Drug Administration have published amendment 21 CF which permits the use of FEP and PFA as articles or components of articles intended for use in contact with food. There is no general approval for use of these grades in medical applications. COE ATEIALS The core material is the component which imparts life or memory to the encapsulated O-ring when it is subjected to compressive force. VITON A fluoroelastomer compound with a combination of exceptional mechanical properties and compression set resistance. This particular energizer gives an O-ring excellent memory and the ability to recover rapidly from deformation. This core has a Shore A hardness of 75 with a suggested operating temperature range of -10 F to +300 F (-23 C to +150 C) in encapsulated applications. SILICONE This elastomer possesses mechanical properties similar to Viton, with the exception of its slightly lower compression set resistance. It is more suitable for sensitive applications where lighter compressive forces are applied to energize the seal. This core has a Shore A hardness of 70 but it also offers a broader operating temperature range of -80 F to +500 F. (-62 C to +260 C) James St. Zeeland, I 49464, SA

12 ASTA SEAL The spring energizer, made from precision rolled stainless high strength steel gives a very high compression set resistance. The stainless spring core maintains its resilience during in long term exposure to cryogenic temperatures -420 F to +500 F (-250 C to +260 C). It offers superior sealing characteristics in face seal applications, especially in liquid oxygen and hydrogen service. HOLLOW COE Hollow core O-rings provide effective sealing properties in applications where lower compressive forces may limit sealing ability of our standard O-rings. The combination of a hollow core insert with a slightly lower hardness offers a more flexible, easier to squeeze O-ring requiring less energy to activate its sealing capability. Note: Hollow core energizers are available in a limited size range. Please contact Vedovell for specific details.

48 Custom oldings

49 Custom oldings Custom olded parts are very design specific. Whether they are compression, injection or transfer molded, Vedovell has years of experience providing customers with custom molded parts that are unique to their application. Our custom molded part experience incorporates the certification of the material within the confines of each specification, while meeting and overseeing necessary quality reports. Compression olded Custom Parts This process is typically used when an application calls for high quantities in production runs, medium shore in durometer or hardness, or if the material call-out is one that requires less coon, but more expensive materials. An excess of your chosen material is placed into the cavity of the mold to guarantee total cavity fill. Heat and pressure are applied, which causes the rubber compound to flow and fill the cavity, with any overflow going through the overflow grooves. This overflow, or flash, can be a concern when the parts are of critical dimension, larger diameter or of a more expensive variety of a rubber compound. Compression molding reduces the amount of flash created in the molding process. Further reduction of this flash on your custom molded part is done in the deflashing process for any type of molding you may choose. Depending on your parts specifications, this deflashing is done either by tear triing, tumbling, grinding or cryogenic deflashing. Injection olded Custom Parts This very automated process is coonly used for simple designs that have a high quantity required for production. The rubber compound is heated to such a degree that it can flow with ease through a number of runners into the mold, after being injected under pressure from its heating chamber. This process can be ideal, but for just the right compound and the right application. Liquid Injection molding (LI) Liquid injection molding is done very similar to standard injection molding. The mold is heated and closed before uncured rubber is injected into the mold. One difference is liquid injection materials come in pails or barrels and are two parts mixed together; one being the catalyst which uses platinum in the process, the other being liquid silicone. The curing time is much shorter than with a typical injection process. This will often lead to a lower cost with high volume requirements. The raw materials are also received in sealed containers and are typically pumped directly from the barrels to the machine, significantly decreasing any contamination. It is a preferred form of molding in the medical industry as it is considered a closed molding system. Vedovell is able to provide product certified to a Class VI environment. Transfer olded Custom Parts This process is different than compression molding. Your material is placed in a pot below the top plate and above the gates, creating an even flow of material into the cavity. The rubber compound is then forced from the pot and into the gates. With your finished product, you will see what are known as gate marks, which indicate where gates come into play with the cavity James St. Zeeland, I 49464, SA

50 Extruded ubber

51 Extruded ubber The use of extruded seals is extremely diverse. You will find extrusions in many types of manufacturing processes for a variety of purposes. Applications include, but are not limited to: door and window seals in the architectural environment and automotive, appliance and aircraft industries; bearing seals; bumpers; heater gaskets; radiator overflow tubing; vacuum cleaner belts; ladder foot grips, and cushions on bars or handles. The applications are endless and expanding rapidly with innovative engineering of extrudable materials. aterials which can be extruded include dense and sponge rubber from a variety of compounds to meet your specific environment and application. These compounds include Nitrile, EPD, Natural rubber, Neoprene, Viton, rethane, Silicone and many others. Whether your application requires a long or short run, Vedovell will service your needs with the appropriate compound. Extrusions can be diversified for use by many secondary operations such as cut lengths, vulcanized to be endless, and formed and notched to allow a variety of shapes and sizes of products. ost extrusions are custom profiles which are tooled to meet your blueprint requirements. This is an extremely competitive method of manufacturing due to reasonable tooling costs. There are also standard cord (rod), tubing and channels available.

56 Oil Seals

57 Oil Seals Oil Seals are a good resource for any application where foreign media such as oil, grease and dust are concerns. A variety of Lip, Case, and Spring materials are available for your review while you make your seal selection. Lip, Case and Spring aterials Lip aterials Nitrile Buna-N 70 durometer compound is the standard material for our seals and is recoended for a majority of coon applications. Nitrile lip seals work well within the temperature range of -65 F to 250 F and provide compatibility with water and most coon mineral oil and greases. Polyacrylate compounds are recoended for higher temperature applications, ranging from -30 F to 300 F. They also work well with mineral oils, EP additives and greases. However, they offer poor sealing in dry running conditions and cost more than Nitrile. Silicone compounds offer the widest range of normal operating temperatures ranging from -90 F to 340 F. However, they do not perform well in dry running conditions, and should not be used with EP compounds and oxidized oils. Viton compounds are premium lip materials offering the widest temperature range and chemical resistance. Viton will handle temperatures from -40 F to over 400 F (-40 C to over 240 C). Viton will resist most special lubricants and chemicals that can destroy Nitrile, Polyacrylates and Silicones. Viton is extremely resistant to abrasion and provides superior wear performance. Viton works in dry running applications, but only for intermittent periods. Graphite is available as an additive to any compound. Normally graphite is added at a 3% factor to aid in lubricity. Case and Spring aterials The cases and springs for our seal products are produced from carbon steel. In applications where corrosion resistance is important, either case or spring or both can be produced from stainless steel. In addition, rubber coated seals can provide the best resistance to corrosive environments in the most economical design. HYPALON coating is an O.D. sealant which is available on any metal case design by customer request. Lip, Case and Spring Tables The following tables identify the most coon lip and case designs. Additional, more complex designs are available for special applications; however, the lip and case designs below represent those which will fill the needs of most seal requirements. Lip Design The following designations indicate the configuration of the sealing members: V = Single Lip K = Double Lip S = Single Lip, Spring Loaded OB = Oil Bath (Prefix) T = Double Lip, Spring Loaded WS = Wiper w/bronze Scraper = Triple Lip D = Double Lip, Double Spring Loaded WP = Wiper Lip Design O = External Seal Type James St. Zeeland, I 49464, SA

58 Case and Spring Design The following designations indicate the case type or any special features of the basic case designs. The designations for lip designs, attachment configuration and case style are then put together to indicate the specific seal type desired. A = Double Case B = Lip Attached to End of Case Only C = Fully ubberized Casing E = etal einforced Sealing Lip F = Special Fully Encased Design G = idged ubber Coated O.D.

61 Spring Energized Seals

62 Spring Energized Seals Due to the nature of spring energized seal applications, a wide range of available seal jacket and seal spring materials are offered to customers to provide an engineered product that fits with the entire scope of their various applications. Spring energized seals are a last resort for most companies that consider using them in their application. Typically, by the time a company has to resort to the use of a spring energized seal, all other attempts at using more conventional seals have failed. This is exactly why such a wide range of materials for these seals are available; to provide the right combination of materials to completely meet the specifications set by the parameters of an application. This section will touch on seal jacket materials, seal spring materials and describe their use. Seal Jacket aterials Seal Jacket aterials fall into four general categories: PTFE (Virgin Teflon, Filled PTFE, Alloyed PTFE and Thermoplastics. Each has specific application niches, with benefits as well as shortcomings. An attempt will be made to inform the reader of the relative shortcomings of each material so that you may be aware of potential trouble spots when applying a material to specific applications. PTFE PTFE is the premium of spring energized seal materials. It is readily available from a number of sources in resin form or as compression molded shapes. For seals, the material should be processed for maximum amorphousity (highest elongation, smallest grain structure). PTFE is excellent for most low and medium pressure static applications. PTFE will handle temperatures up to approximately 350 F without sacrificing most of its properties. It is excellent for dynamic applications where speeds and/or cycles are minimal. It provides the lowest friction of any seal material and is also very kind to the metal speed operation. Filled PTFE 5% olybdenum Disulphide Filled PTFE. 5% oly filled PTFE is used for increased temperature (up to 400 F) and pressure applications. It provides good sealing characteristics (low compressive modulus) while offering better extrusion resistance and lower wear than unfilled PTFE. It is useful for liquids and gasses where high temperatures, pressures and cycling rates are present. It loses some sealability to PTFE in lower temperature and pressure applications. It should be processed for maximum amorphousity. 15% Graphite Filled PTFE 15% Graphite filled PTFE is useful at high temperatures (up to 500 F). It is generally used for liquids and steam at moderate (up to 3,000 psi) pressures. Because of the heavy fill, the material becomes somewhat porous to high pressure gasses. It should be processed for maximum crystallinity. 15% Glass, oly Filled PTFE 15% Glass, oly Filled PTFE material was developed for sealing at very high pressures. With the right jacket design, pressures up to 40,000 psi have been successfully sealed with this material. Like 15% graphite filled PTFE, it has some porosity to high pressure and temperature gasses, however, may be the only choice in very high pressure gas systems. It should be processed for maximum crystallinity James St. Zeeland, I 49464, SA

63 Alloyed PTFE PTFE/yton alloy is a required material for seal applications involving very high speed reciprocating or rotary motions. It has a high temperature rating (up to 575 F) that makes it an excellent general purpose material with mid-range pressure requirements. Thermoplastics HW Polyethylene HWPE has two exceptional characteristics which make it an excellent choice for spring energized seals. It is an extremely abrasion resistant material and may be used with an abrasive media such as paint or fluids with high levels of particle contamination. It is also FDA approved for elongation properties at cryogenic temperatures. It is the best choice for cryogenic pumps, valves, etc., however, it should not be used at temperatures above 180 F. G HW Polymer G HW, extremely close in relation to HW, has the following advantages: superior performance against virtually all acids, solvents, salts, etc; zero moisture absorption; and superior wear surface to nylon and other materials. Because of its self-lubricating, non-stick and wear-resistant characteristics, G HW has been used in such applications as ore/coal, cement, gravel and mining industries. As its sister material, HW, G has a temperature limit, it is 140 F. Hytrel (DuPont Polyester Elastomers) Hytrel is included as a material because of its high resistance to radiation. It should be specified in all nuclear applications, valves, cylinders, actuators, pipe snubbers, etc. Seal Spring aterials and Designs The primary function of the spring is to provide energy to the sealing jacket for effective sealing at low system pressures. The spring also is used to compensate for the low resiliency or lack of memory of the jacket materials in relation to wear in dynamic applications. When operating conditions permit, an elastomer energizer may be used as an alternative to the metal energizer. 301 Stainless Steel Spring-IL-S-5059 This stainless steel is the general purpose spring material. It may be used in applications involving most corrosive chemicals at all ranges of pressure and moderate temperatures. Elgiloy Spring Elgiloy is an extremely strong cobalt/nickel alloy used in highly corrosive environments. V- Finger Spring The V- Finger Spring is designed to provide maximum deflection capability. Designing for deflection provides a low rate spring. Having a low rate spring heavily deflected provides a fairly constant spring load transmittance to the sealing lip throughout most dynamic applications. It is most useful if wear compensation, low constant friction or high shaft runouts and/or disparities are design requirements. Helical Wound Spring The Helical Wound Spring is designed especially for maximum load capability. Designing for load provides a high rate spring useful for applications where maximum contact pressure is desired to provide minimum leakage. It is useful in most static applications and in dynamic applications where shaft runouts are low and sealing requirements are stringent James St. Zeeland, I 49464, SA
